USING THE IBM JDK If you are using the IBM JDK, remove the saaj-api jar from the installDir/lib/endorsed library using the following command: rm lib/endorsed/org.apache.servicemix.specs.saaj-api-1.3-2.7.0.jar Before invoking the ./bin/fuse script:, set the JAVA_OPTS environment variable as follows: JAVA_OPTS=-Xshareclasses:none 5
Red Hat Fuse 7.2 Installing on Apache Karaf CHAPTER 4. ADDING A REMOTE CONSOLE USER Fuse on Karaf is not installed with a default user for the remote console. You must add a user before you can connect to the server’s remote console. To add a user, edit InstallDir/etc/users.properties. IMPORTANT The information in this file is unencrypted so it is not suitable for environments that require strict security. To add a user: 1. Open InstallDir/etc/users.properties in your favorite text editor. 2. Locate the following lines: #admin = admin,_g_:admingroup #_g_\:admingroup = group,admin,manager,viewer,systembundles,ssh Note that the first line has the syntax USER=PASSWORD,_g_:GROUP,ROLE1,ROLE2,.... In this example, the first line specifies a user, admin, with the password, admin, and the role group, admingroup. 3. Uncomment both lines by removing the leading # character. 4. Change the first admin to the desired user name. 5. Change the second admin to the desired password. 6. Save the changes. 6
CHAPTER 5. OFFLINE MODE CHAPTER 5. OFFLINE MODE You can run the Apache Karaf container in offline mode (that is, without an Internet connection). But if you are planning to deploy custom applications to the container, it might be necessary to download additional dependencies to a local Maven repository before you can run the container in offline mode with these applications. To run the Apache Karaf container in offline mode, it is necessary to distinguish between the following kinds of dependency: Runtime dependencies — the dependencies required to run the Apache Karaf container, in its default configuration. Build-time dependencies — the dependencies required to build a custom application (which might include third-party libraries). Here is a summary of what can be done in offline mode and what needs to be done in online mode (with an Internet connection): Running the Apache Karaf container in its default configuration— is supported in offline mode. The default configuration of the Apache Karaf container is specified by the featuresBoot property in the etc/org.apache.karaf.features.cfg file. The requisite dependencies are all provided in the system/ sub-directory of the installation. Installing additional features — is, in general, not supported in offline mode. In principle, you can use the features:install command to install any of the features from the standard feature repositories (as specified by the featuresRepositories property in the etc/org.apache.karaf.features.cfg file), but the majority of these features must be downloaded from the Internet and are thus not supported in offline mode. Deploying custom applications — is, in general, not supported in offline mode. There may be some cases where an application with a minimal set of build-time dependencies is deployable offline, but in general, custom applications would have third-party dependencies that require an Internet connection (so that JAR files can be downloaded by Apache Maven). If you do need to deploy an application with dependencies that are not available offline, you can use the Maven dependency plug-in to download the application’s dependencies into a Maven offline repository. This customized Maven offline repository can then be distributed internally to any machines that do not have an Internet connection. 5.1. DOWNLOAD REPOSITORY FOR MAVEN PROJECT From the project directory that contains the pom.xml file, run the following Maven command: mvn org.apache.maven.plugins:maven-dependency-plugin:3.1.0:go-offline - Dmaven.repo.local=/tmp/foo All the Maven dependencies and plug-ins required to build the project will be downloaded to the /tmp/foo directory. 5.2. ENABLE OFFLINE MODE To enable offline mode you must edit etc/org.ops4j.pax.url.mvn.cfg. Find the setting org.ops4j.pax.url.mvn.offline and replace the default false with true. 7

APPENDIX A. INSTALLING THE APACHE COMPONENTS APPENDIX A. INSTALLING THE APACHE COMPONENTS Red Hat Fuse provides an additional package to download, which contains the standard distributions of Apache Camel and Apache CXF. If you want to use a standard distribution of Apache Camel or Apache CXF (without the OSGi container) use the archived versions in the downloaded extras package. A.1. GETTING THE EXTRAS ARCHIVE You can download the extras archive from the Red Hat Customer Portal→Downloads→Red Hat JBoss Middleware→Downloads page, after you register and log in to your customer account. Once logged in: 1. Select Fuse, listed under Integration Platforms, in the sidebar menu. 2. Select 7.2.0 from the Version drop-down list on the Software Downloads page. 3. Download fuse-extras-7.2.0.fuse-720050-redhat-00001.zip archive. A.2. CONTENTS OF THE EXTRAS ARCHIVE The extras archive file contains the following archive files nested inside it: apache-camel-2.21.0.fuse-720050-redhat-00001.zip apache-cxf-3.1.11.fuse-720057-redhat-00001.zip You can copy these files to the desired location and decompress them using the appropriate utility for your platform. WARNING Do not unpack an archive file into a folder that has spaces in its path name. For example, do not unpack into C:\Documents and Settings\Greco Roman\Desktop\fuse. 9
Red Hat Fuse 7.2 Installing on Apache Karaf APPENDIX B. PREPARING TO USE MAVEN B.1. OVERVIEW This section gives a brief overview of how to prepare Maven for building Red Hat Fuse projects and introduces the concept of Maven coordinates, which are used to locate Maven artifacts. B.2. PREREQUISITES In order to build a project using Maven, you must have the following prerequisites: Maven installation — Maven is a free, open source build tool from Apache. You can download the latest version from the Maven download page . Network connection — whilst performing a build, Maven dynamically searches external repositories and downloads the required artifacts on the fly. By default, Maven looks for repositories that are accessed over the Internet. You can change this behavior so that Maven will prefer searching repositories that are on a local network. NOTE Maven can run in an offline mode. In offline mode Maven only looks for artifacts in its local repository. B.3. ADDING THE RED HAT MAVEN REPOSITORIES In order to access artifacts from the Red Hat Maven repositories, you need to add them to Maven’s settings.xml file. Maven looks for your settings.xml file in the .m2 directory of the user’s home directory. If there is not a user specified settings.xml file, Maven will use the system-level settings.xml file at M2_HOME/conf/settings.xml. To add the Red Hat repositories to Maven’s list of repositories, you can either create a new .m2/settings.xml file or modify the system-level settings. In the settings.xml file, add repository elements for the Red Hat repositories as shown in Adding the Red Hat Fuse Repositories to Maven .

Red Hat Fuse 7.2 Installing on Apache Karaf B.4. ARTIFACTS The basic building block in the Maven build system is an artifact. The output of an artifact, after performing a Maven build, is typically an archive, such as a JAR or a WAR. B.5. MAVEN COORDINATES A key aspect of Maven functionality is the ability to locate artifacts and manage the dependencies between them. Maven defines the location of an artifact using the system of Maven coordinates, which uniquely define the location of a particular artifact. A basic coordinate tuple has the form, {groupId, artifactId, version}. Sometimes Maven augments the basic set of coordinates with the additional coordinates, packaging and classifier. A tuple can be written with the basic coordinates, or with the additional packaging coordinate, or with the addition of both the packaging and classifier coordinates, as follows: groupdId:artifactId:version groupdId:artifactId:packaging:version groupdId:artifactId:packaging:classifier:version Each coordinate can be explained as follows: groupdId Defines a scope for the name of the artifact. You would typically use all or part of a package name as a group ID — for example, org.fusesource.example. artifactId Defines the artifact name (relative to the group ID). version Specifies the artifact’s version. A version number can have up to four parts: n.n.n.n, where the last part of the version number can contain non-numeric characters (for example, the last part of 1.0- SNAPSHOT is the alphanumeric substring, 0-SNAPSHOT). packaging Defines the packaged entity that is produced when you build the project. For OSGi projects, the packaging is bundle. The default value is jar. classifier Enables you to distinguish between artifacts that were built from the same POM, but have different content. The group ID, artifact ID, packaging, and version are defined by the corresponding elements in an artifact’s POM file. For example: ... org.fusesource.example bundle-demo bundle 1.0-SNAPSHOT ... For example, to define a dependency on the preceding artifact, you could add the following dependency element to a POM: 12
APPENDIX B. PREPARING TO USE MAVEN ... org.fusesource.example bundle-demo 1.0-SNAPSHOT ... NOTE It is not necessary to specify the bundle package type in the preceding dependency, because a bundle is just a particular kind of JAR file and jar is the default Maven package type. If you do need to specify the packaging type explicitly in a dependency, however, you can use the type element. 13
